Saturn's moon Rhea may have a breathable atmosphere (unlikely)
- olefoo 16y agoBreathable only if you can tolerate frozen lungs and a ppO2 of nothing since oxygen is a liquid at the temperatures found on Rhea's surface (-174 C). I realize io9 is a science _fiction_ blog, but I wish they would put more emphasis on the science sometimes.
- hugh3 16y agoIs oxygen a liquid under those temperature and pressure conditions? Not much is a liquid at the damn-near-zero pressure of Rhea's atmosphere.
- olefoo 16y agoI thought of that not long after I hit the post button. And you are correct. But basically, there may be free oxygen on Rhea, but no stretch of the imagination is going to turn that into anything like a breathable atmosphere.
